what about downtown mississuaga? that's even closer to Toronto than Hamilton. brampton has direct train to its downtown.. or vaughn, they are getting the subway there. Markham also has GO and YRT!
won't concentrating things in downtown hamilton mean more sprawl along the qew, highway 6, 403, and 8 :p hamilton doesn't even have lrt or subway, go service is terrible, won't that just mean people will drive to their jobs?
edit: oh yeah..... 'hi', Toronto + Hamilton = good, rest of 905 = bad/sprawl/leeches, scarborough = urban, scarborough town centre > downtown missisauga , "you guys don't care about the city like I do", downtown is dying etc etc etc
